"Could not find module" after spago install — why doesn't the new package resolve?

I'm setting up a repeatable PureScript development environment with Spago (PureScript compiler 0.15.x, recent Spago) and keep hitting a module resolution failure I don't fully understand. After running spago install purescript-aff , importing Effect.Aff in a source file and running spago build fails with an error along the lines of Could not find module Effe

Gitter API message editing limits and event synchronization

The Gitter REST API provides an update operation for individual messages within a room using the message ID. While this functionality allows the author to modify previously sent content, the documentation does not specify a temporal window during which these edits are permitted. Furthermore, there is uncertainty regarding how remote clients are notified of t

Eclipse Secure Storage ↔ OS Credential Store: Least‑Privilege and Expired Credential Handling

The goal is to understand how Eclipse’s Secure Storage interacts with the host operating system’s credential store to enforce least‑privilege access and manage expired authentication tokens across Windows, macOS, and Linux. Eclipse stores sensitive data encrypted with a master password, optionally delegating encryption to OS keychains, but the runtime permis

NHibernate N+1 selects on lazy collections: batch-size in mappings or query-level Fetch for diagnosis and fix

Symptom A screen that loads a list of parent entities and touches a lazy child collection per row issues one SQL statement for the parents plus one per parent row, visible in NHibernate.SQL output as repeated near-identical selects. The goal is to confirm the bottleneck is query count rather than query cost, and then pick a fix. Constraints and uncertainty N

Client cannot reach the tmux server socket: stale socket versus exit-empty policy

tmux is a client/server program. Each client command connects to a long-lived per-user server over a local Unix domain socket, by default inside a tmux-<uid> directory under the temporary directory and overridable with TMUX_TMPDIR . No name resolution and no certificate validation occur on that path, so resolver and TLS diagnostics do not apply to a cl

Which documents remain resident after Couchbase Server reaches its low-water mark?

Which documents remain resident after Couchbase Server reaches its low-water mark? The goal is to understand the residency behavior of documents in a Couchbase bucket when memory pressure triggers the managed cache ejection policy. Couchbase Server keeps keys and metadata resident while values may be ejected based on an NRU policy once the bucket’s low‑water

Realm Kotlin SDK ↔ AndroidX Lifecycle instance ownership and listener cleanup

Designing ownership boundaries for Realm instances and change listeners when an Android screen is tied to AndroidX Lifecycle requires a clear interoperability contract between the Realm Kotlin SDK and Lifecycle components. The SDK is thread-confined and historically requires explicit close. RealmChangeListeners and Kotlin Flows derived from Realm objects can

Kali Linux automatic autoremove policy for orphaned packages in low-traffic deployments

Goal: minimize disk footprint on Kali Linux instances that experience long periods without package changes by automatically removing orphaned libraries. Constraint: the rolling release does not define an automatic autoremove trigger based on package activity inactivity, leaving cleanup to manual apt-autoremove scheduling. Uncertainty: what inactivity thresho

Pub/Sub emulator bypassing IAM enforcement during local testing

The Google Cloud Pub/Sub emulator allows for local development by setting the PUBSUB_EMULATOR_HOST environment variable. However, when active, the emulator bypasses standard OAuth 2.0 token validation and IAM permission checks. This current permissive behavior creates a discrepancy between local testing environments and production. While the emulator accepts
